And then, there's the folly of being "brand specific".
Only two manufacturers make most all common batteries ; Delphi sold to, Johnson Controls and there is Exide.
Now, comes the new "Dual Carbon" battery. It takes a charge 20 times faster than lithium ions.
It lasts for three times the charge cycles of lithium ions.
Johnson controls also makes some or all of these batteries as well.
Acura, Advance Auto Parts, Autocraft, Western Auto, Tough One, Alliance, American Hardware, Ames, Varta, Blains Farm & Fleet, Battery Alliance, Bosch, Carrefour(Europe), Champion, Amara Raja Batteries LTD(Joint venture with Johnson Controls India),Varta, Optima Batteries, LTH, and Heliar are all battery manufactures owned by Johnson Controls.
Johnson Controls supplies Ford Motor company, Diamler Chrysler, Honda, Toyota, Nissan, and Isuzu with original equipment batteries.
So next time you go and buy a battery for a automobile chances are its a battery made by Johnson Controls.
The scary part is, where does Vex and Wally World get theirs ? CHINA!!!
